the only way they would ever know is if you live where an vehicle inspection / certification is required for license renewal. not something the majority have to do. the ones i have heard that have had an issue are just required to meet the idiot requirements. no impound or fine, not unlike having a tuner in place.

Sorry laj.... I think your information is a generation of trucks outdated... the current trucks are proving to be reliable with EGR, DEF, DPF.

a friend of mine just spent 13k last yr. alone on his isx 485hp on egr dpf alone, he'll be happy his truck and engine are outdated. oh ya, its a 2014
another friend of mine has a 525 isx, he's putting a kit together, cant afford the downtime due completely to emission problems. got about 50-60 friends all having the same problem, all trucks 2014 up to 16, one less then 2 months old, been in shop for a week now, outdated?????

Unfortunately they still have emission problems. I just bought a new 2016 2500 chevy duramax about a month ago. I owned it a total of about 80 hrs and 200 miles before the check engine light came on. Back to dealer for a day. Some sensor in the emissions system. Got it back and next day kept flashing on screen, keep driving regeneration in progress. I didn't have time for that. Finally after 3 days it quit saying that. When it regens, the fuel mileage is horrible. Hopefully it will get better.

Mine weighs 11600 empty 14000 loaded 23000 gross Ram 3500 Srw . 3yrs pulls great no swaying done up to 700 in a day never wanted a dually and never regretted getting one. Disc brake upgrade stops on a dime!

DRWs are on the way out. Just look on the highways and CGS. The owners are getting smarter and towing much larger units with SRWs these days.
I have towed over 14000 lbs with SRWs for 18 years with great satisfaction and stability.
Enjoy.

Single or double rear wheels do not dictate the speed they can travel. The final gear ratio and the driver are the two major contributors, of course trying to pull a 28,000 pound trailer with a 4 cylinder Nissan would contribute.

Owners getting smarter???? Not really, SRW trucks are rated higher than a dually of years past. We are finding that here, the guys that bought a dually 10 years ago because they needed the capacity, are running single wheel trucks today. Our F350 is slightly over on GVW with our lightly loaded Mobile Suites. It handles the load just fine, however we are looking for a 350 DRW or 450. We want a lwb truck, and where we are slightly over the GVW of the current truck, If I'm upgrading anyways, I'm going to have enough truck.
